Stewart, who has a daughter aged seven months, said she had done it “for a laugh”.

Many online readers reacted with disgust and posted angry comments about Stewart’s treatment of the youngster.

Now a page claiming to defend Stewart has been set up on Facebook but actually aims a stream of vile abuse at those condemning the mum - as well as posting sick pictures and jokes about those suffering from Down's Syndrome.

It states: "Courtney Stewart is a single mother whose only crime was to think that her disabled child is just as entitled to play as any other kid.

"Why the hell does every second idiot on the planet seems to feel they have the right, nay the social obligation, to grab a torch and pitchfork and run shrieking abuse and invective into the night sky as soon as they see anything online they fail to understand?"

However, sample replies to people furious about the page defending Stewart include: "Oh just log off, you cretinous mong (a derogatory term for people suffering from Down's Syndrome) breeder", and: "Lose some weight, you fat mess."

Yesterday a reporter approached Stewart at her home in Erskine, Renfrewshire, to show her the footage.

At first she refused to answer her door.

But after watching the clip, she says: "We're playing.

"What are you trying to do, ruin my life?"

A male voice then says: “Shut the door in their face,” before she slams the door.

But the mobile phone footage from a children's soft play centre is arguably more horrifying and upsetting.

The person who passed the video to us said: "It was horrendous to watch.

"She throws him from above her shoulder and he lands with a terrible jolt.

"He then crawls away before she grabs him by his ankle.

"It was unbelievable to watch him be dragged by the ankle like that.

"When she throws him down you can tell that the person filming it has had a shock at the force of the landing, because the images jolts a bit."

The images were shot on May 28 and given to the Daily Record in the aftermath of the washing machine story.

The source added: "It might be a bouncy castle, but it is meant to be for children to jump up and down on.

"It is not supposed to be for an adult to lift kids to shoulder height and throw then down like that.

"The force of the landing is sickening.

"It is hard to watch.

"This wee boy could have suffered an injury because of the force he lands with and the way his neck moves.

"Something has to be done about this."

When the Record confronted Stewart over the washing machine incident, she told us it was "ridiculous" that someone had reported her to police and claimed the youngster "loved" washing machines.

After she posted the image on Facebook, people sent her abusive comments and she was grilled by the police for more than an hour at her home.

She was also allegedly attacked by a woman on her doorstep.

The bouncy castle footage was shot at Pandamonium play centre in Erskine.

The Record's source added: "It happened so quickly.

"There is no criticism of the staff here.

"They are diligent and well- trained.

"I thought about flagging it up but I decided against it at the time.

"That changed when I saw the washing machine story in the Record."

We approached Stewart to show her the footage but she said: "So what?

"It's me playing.

"It is me playing with the boy at Pandamonium.

"What are you trying to do to me?"

Staff at the centre were shocked shown the video.

Joint owner John Hay said: "Our staff are trained to be very vigilant and diligent.

"I am disappointed this happened and we were not made aware of it at the time."
